+PBL-based image generation
+==========================
+Changes only the required register bit in in PBI commands.
+
+Provides reference code which might needs some
+modification as per requirement.
+example:
+By default PBI_SRC=14 (which is for IFC-NAND/NOR) in rcw.cfg file
+which needs to be changed for SPI and SD.
+
+For SD-boot
+==============
+1. Set RCW[192:195], PBI_SRC bits as 6 in RCW file (t1040d4_rcw.cfg type files)
+
+example:
+ RCW file: board/freescale/t104xrdb/t1040d4_rcw.cfg
+
+Change
+66000002 40000002 ec027000 01000000
+to
+66000002 40000002 6c027000 01000000
+
+2. SD does not support flush so remove flush from pbl, make changes in
+   tools/pblimage.c file, Update value of pbl_end_cmd[0] = 0x09138000
+   with 0x091380c0
